In January, Intel Corp. enhanced its Centrino mobile technology platform by upgrading its Pro/Wireless network adapter from 802.11b to faster 802.11g connectivity. Now the chip giant has made an even bigger improvement, using smaller transistors: Three new Pentium M processors are Intel's first built with 90-nanometer instead of 0.13-micron process technology, as well as the first to feature model numbers instead of simple clock-speed listings.
Formerly known by the codename "Dothan," the Pentium M 735 (1.7GHz), 745 (1.8GHz), and 755 (2.0GHz) combine 90-nanometer manufacturing with strained-silicon technology to give its transistors a speed boost. They plug into the same sockets and have the same 400MHz front-side bus as previous Pentium M chips, but feature 2MB instead of 1MB of power-managed Level 2 cache as well as microarchitectural improvements including an enhanced register access manager and data prefetcher for up to 10 percent higher performance at the same clock speed.
Rated at 21 watts thermal design power (versus 24.5 watts for their predecessors), the Pentium M 735, 745, and 755 are priced at $294, $423, and $637 respectively in 1,000-unit OEM quantities. All support Intel's Enhanced SpeedStep Technology to optimize application performance and power consumption for longer battery life.
